A crise do casamento contemporâneo: um estudo psicossocial

A atual família nuclear urbana e a instituição do casamento passam por momentos difíceis. Profundas mudanças sócio-econômicas levaram o casamento contemporâneo a um estado de crise caracterizado pelo aumento do número de separações a tal ponto que aproximadamente, cinquenta por cento das uniões, nos dias de hoje, tendem à ruptura em poucos anos. Na primeira parte de nosso trabalho expomos os fatores aparentemente responsáveis por essa situação. Assim, a diminuição da religiosidade, a modernização e a industrialização, o encurtamento das famílias, a excessiva e acrítica valorização do amor como base única do casamento e solução para todos os males, o aumento da longevidade, ·a revolução sexual, um estilo de vida que privilegia um individualismo exarcebado, a emancipação feminina, a menor integração social na comunidade e o isolamento excessivo seriam .as principais causas da crise e da configuração do que denominamos - pelo fechamento e isolamento resultantes - de família. Com os objetivos de testar uma série de hipóteses relacionadas à propensão ao divórcio e de contrastar o que pensam os estudiosos da área com o que as pessoas no seu dia a dia consideram como causas da crise, expomos na segunda parte de nosso trabalho os resultados de pesquisa realizada com quatrocentos sujeitos de classe media, distribuídos em quatro condições: jovens solteiros, casados, separados e casados idosos (metade do sexo masculino, metade do feminino). Através de questionários criados para esse fim, comparamos as avaliações pessoais em função das diferenças de estado civil, faixa etária e sexo, nos quatro grupos - outra de nossas metas. Abordamos também a aplicação de alguns princípios da psicologia social a nossa área de estudos. Para tanto incluímos nos questionários perguntas tendo como embasamento teórico (a) as hipóteses de Jones e Nisbett sobre perspectivas divergentes na atribuição de causalidade entre atores e observadores, (b) a percepção de ineqüidades existentes na relação entre homens e mulheres e suas consequências (tópicos em justiça distributiva) e (c) a divisão de poder no casamento. As conclusões de nosso trabalho estão na última seção, onde são sumarizadas e relacionadas como exposto na primeira parte as hipóteses que confirmamos: a hipervalorização do amor, principalmente entre os mais jovens, a crescente secularizaçao e suas implicações, o movimento feminista, o espírito individualista reinante e o grande número de relações extramaritais são alguns dos principais fatores que contribuem para a dissolução das uniões. Verificamos ainda, além de distintas visões do casamento por parte de homens e mulheres, a relação entre a percepção de inequidades no casamento e insatisfação conjugal, a existência de perspectivas divergentes em termos de atribuição causal entre atores e observadores e uma divisão mais igualitária de poder entre casais jovens.

Performance of incentive contracts in highway PPP projects in Brazil

Private-Public Partnerships (P.P.P.) is a new contractual model institutionalized in 2004 that could be used to remedy to the infrastructure deficit in Brazil. In a context of a principal and agent relation, the public partner goal is to give incentives to the private partner in the contract so that their interests are aligned. This qualitative research presents the findings of an empirical study examining the performance of incentive PPP contracts in Brazil in the highway sector. The goal is to explain how the contracting parties can align their interests in an environment of asymmetric information. Literature identified the factors that can influence PPP design and efficient incentive contracts. The study assesses the contribution of these factors in the building of PPP contracts by focusing on the case of the first and only PPP signed in the highway sector in Brazil which is the MG-050. The first step is to describe the condition of the highway network and the level of compliance of the private partner with the contract PPP MG-050. The second step is to explain the performance of the private partner and conclude if the interests of both partners were aligned in contractual aspects. On the basis of these findings and the analysis of the contract, the study formulates suggestions to improve the draft of PPP contracts from the perspective of the incentive theory of contracts.

Wasted: understanding the economic and social impact of food waste

Over one-third of global food production goes to waste while over 850million people are fighting chronic hunger. The United States is the world’s largest food waster. One third of America’s food with an economic value of US$161 billion is wasted and less than 7% is recycled. American food waste ends up in landfills creating powerful methane gas emissions. South Korea, on the other hand, has implemented the world’s strictest food waste laws, and today diverts 93% of wasted food away from landfills turning such waste into powerful economic opportunities. This Master Thesis investigates the reasons behind global food waste by comparing South Korea and the US. It explores what these two nations are doing to address their respective food waste problems, South Korea successfully, the US not. The paper looks at the two countries’ respective policies and national characteristics, which impact decision-making and recycling processes. The effort concludes that South Korea has embarked on a necessary paradigm shift turning food waste into powerful economic drivers leading to a sharp decline in food waste. In the US, food waste continues to be a major problem without a national strategy to remedy waste. Any effort in the US, while laudable, is sporadic and local, and hence the US misses out on possibly important economic growth opportunities.

Resposta gerencial à ruptura: o efeito de compensações no comportamento do consumidor

A falta de estoque continua sendo um problema no varejo. O progresso foi limitado, nos últimos quarenta anos as estimativas dos níveis de ruptura têm constantemente ultrapassado a média de 8,0 %. Hoje, como no passado, o gestor precisa lidar com o consumidor frente à ruptura. O propósito desta pesquisa foi investigar a eficácia de cinco formas de compensações: pedido de desculpas, vale, entrega em domicílio, troca por outro item de preço ligeiramente superior e desconto como um mecanismo para induzir o consumidor a não deixar a loja frente a uma ruptura. Além da reação geral do consumidor, também foi examinado como algumas características do consumidor (fidelidade a marca) e a situação da compra (urgência da compra) influenciam o efeito de cada forma de compensação na reação do consumidor. Em geral, os resultados do estudo mostraram que as compensações funcionam. O pedido de desculpas é a forma de compensação menos eficiente, aparentemente aumenta a percentagem de consumidores que deixam a loja em reação à ruptura Esta pesquisa sugere que existem oportunidades para varejistas utilizarem as compensações como mecanismo para gerenciar a ruptura.

Nem tão racional assim: cognição social implícita, discriminação trabalhista e ações afirmativas

É um trabalho de interdisciplinaridade entre o Direito e a Psicologia Social dentro da temática da discriminação trabalhista. Será apresentada a visão da Psicologia Social sobre preconceitos automáticos (“Implicit Bias”), assim como será discutida qual seria a melhor solução para o problema exposto. Ações afirmativas é o remédio mais adequado para combater preconceitos automáticos. O trabalho mostra a visão da Psicologia Social sobre a melhor forma de introduzir e conduzir as Ações afirmativas no mercado de trabalho. Será também feita uma análise jurídica constitucional e infraconstitucional das Ações afirmativas no mercado de trabalho, procurando entender se o ordenamento constitucional acolhe estas políticas no Brasil, bem como investigar o interesse do Estado em legislar para tornar tais iniciativas uma realidade.

The economics of wage-led recovery: analysis and policy recommendations

The financial crisis and Great Recession have been followed by a jobs shortage crisis that most forecasts predict will persist for years given current policies. This paper argues for a wage-led recovery and growth program which is the only way to remedy the deep causes of the crisis and escape the jobs crisis. Such a program is the polar opposite of the current policy orthodoxy, showing how much is at stake. Winning the argument for wage-led recovery will require winning the war of ideas about economics that has its roots going back to Keynes’ challenge of classical macroeconomics in the 1920s and 1930s. That will involve showing how the financial crisis and Great Recession were the ultimate result of three decades of neoliberal policy, which produced wage stagnation by severing the wage productivity growth link and made asset price inflation and debt the engine of demand growth in place of wages; showing how wage-led policy resolves the current problem of global demand shortage without pricing out labor; and developing a detailed set of policy proposals that flow from these understandings. The essence of a wage-led policy approach is to rebuild the link between wages and productivity growth, combined with expansionary macroeconomic policy that fills the current demand shortfall so as to push the economy on to a recovery path. Both sets of measures are necessary. Expansionary macro policy (i.e. fiscal stimulus and easy monetary policy) without rebuilding the wage mechanism will not produce sustainable recovery and may end in fiscal crisis. Rebuilding the wage mechanism without expansionary macro policy is likely to leave the economy stuck in the orbit of stagnation.

Aplicação simultânea de medidas antidumping e medidas compensatórias

O presente estudo visa esclarecer a possibilidade de aplicar medidas antidumping e medidas compensatórias, de forma simultânea, a um mesmo produto, Desse modo, o referido artigo evidencia a impossibilidade de aplicar ambas as medidas a um mesmo fato gerador, quando for verificada a existência de dumping e de subsídio à exportação, o que constituiria um double remedy. Entretanto, não haveria qualquer proibição acerca da aplicação simultânea das medidas, quando essas forem baseadas em fatos geradores distintos, ou seja, quando no cálculo do montante da medida antidumping aplicada não estiver incluído o valor referente ao subsídio recebido pelo produto, objeto de medida compensatória. Além disso, a interpretação restritiva do artigo leva à conclusão de que a aplicação simultânea de medidas anti-dumping e de medidas compensatórias não seria irregular se o subsídio visado por estas últimas se tratar de subsídio acionável e não proibido

Antitruste: sanção de desinvestimentos em ativos: um estudo de caso no processo administrativo no 08012.11142/2006-79

O presente trabalho é um estudo de caso, tendo como objetivo principal avaliar a sanção de desinvestimentos de ativos, isto é, a pena de cisão de sociedade, transferência de controle societário e/ou venda de ativos, conforme disposto no art. 38, inciso V, da Lei no 12.529/2011 (Lei de Defesa da Concorrência). Para tanto, parte-se da exposição da decisão proferida pelo Tribunal do Conselho Administrativo de Defesa Econômica (Cade) no Processo Administrativo no 08012.011142/2006-79, denominado Cartel de Cimento e Concreto. Tal decisão condenou as empresas fabricantes de cimento e prestadoras de serviços de concretagem a desinvestirem ativos próprios, frutos de aquisição ou de crescimento orgânico. É importante destacar que essa decisão sofreu relevante modificação ao longo do julgamento, decorrente da alteração de entendimento pelos conselheiros do Cade. Em um segundo momento, o trabalho procura propiciar ao leitor uma visão ampla (prós e contras) dos tipos de remédios ou sanções existentes e aplicáveis aos casos em que se determina a medida de desinvestimento, por meio da seleção de alguns casos internacionais e nacionais, escolhidos a partir de casos amplamente tratados pela doutrina, e também citados no julgamento do Processo Administrativo no 08012.011142/2006-79. A seguir, aborda-se a questão do desinvestimento específico ocorrido no Processo Administrativo no 08012.011142/2006-79, buscando-se evidenciar, a partir da análise do aparente choque dos votos do conselheiro-relator e do conselheiro-revisor, que as bases utilizadas para determinação dos desinvestimentos carecem de parâmetros concretos para sua aplicação. Ao final do estudo acerca do desinvestimento, delineia-se uma proposição para solução jurídica. Ao final, conclui-se que a aplicação de medidas de desinvestimentos como penalização por participação em cartel não é escolha fácil, e sua utilização tampouco é pacífica, devendo-se levar em conta alguns aspectos relevantes para que possa ser utilizada de maneira legítima e garantir a sua melhor eficácia.

A mediação como instrumento concretizador do direito fundamental à saúde: uma alternativa à judicialização de conflitos Natal 2013

In Brazil, the 1946 Constitution enshrined the right to health, having it defined as the possession of the best state of health that the individual can achieve. Already the Federal Constitution of 1988 lifted that right to the status of fundamental social right, which transcends the effectiveness and cure of the disease is based on the joint liability of public entities for the provision of a quality service, efficient and prioritize human dignity and comprehensive evaluation of patients. According to the World Health Organization, the definition of health, first characterized as the mere absence of disease, has become recognized as the need to search for preventive mechanisms to ensure the welfare and dignity of the population. Garantista this context, the growing seem lawsuits that deal with the implementation of public policies, especially in the area of the right to health, the omission of which the Government can result in the risk of death. Hence the concern of law professionals about whether or not the intervention of the judiciary in cases that deal with providing material benefits of health care. It claims to break the principle of separation of powers, disobedience to the principle of equality and the impossibility of judicial intervention in the formulation of public policy to try and exclude the liability of public entities. In contrast, the judiciary has repeatedly guardianships granted injunctions or merit determining the supply of materials indicated by the medical benefits that accompany the treatment of patients who resort to a remedy. In this context, mediation, object of study and resolution presented in this work, is presented as an instrument conciliator between the reserve clause and the right to financially possible existential minimum, as it seeks to serve all through rationalization of health services , avoidance of negativistic influence of the pharmaceutical industry, with prioritizing the welfare of the individual and the quality of relationships. This is alternative way to judicialization that in addition to encouraging and developing active citizen participation in public policy formulation also allows the manager to public knowledge of community needs. It is in this sense that affirms and defends the right to health is no longer the mere provision of medical care and prescription drugs, but a dialogue conscious existential minimum to guarantee a dignified life

Abordaje práctico sobre cómo mejorar el bienestar en los bovinos

Current challenges of humanity require a new paradigm for animal production, and invest time and attention to the development of new production techniques that take into account the principles of sustainability and animal welfare science. To do this, we must be committed to promoting animal welfare and health, ensure environmental sustainability, consumer satisfaction and profitability for producers. To change our relationship with animals there is no need for changes in market conditions or large investments, it is enough to know better the needs of the animals we raise, the management system adapted to its characteristics. Even in the most favorable management conditions, on farms that have technological resources and trained personnel, there is much to change, especially in the daily management of the animals. Some of the risks more evident in the traditional systems of beef production are: problems during parturition, morbidity and mortality of calves, lack of shade in the pastures, improper handling of animals, risk of injury, inadequate infrastructure, poor management practices during routine processing (marking, castration, vaccination, dehorning), poor welfare during loading, transport, unloading and slaughter. To remedy this, you can adopt good management practices, which have been shown to reduce risk and improve the welfare of cattle in different stages of the production chain. The objective of this review is to show some of the risks that reduce the welfare of cattle and examples of how the adoption of best management practices impact on improving the productivity of these production systems. Finally, some indicators for assessing welfare in production systems are shown.

Modelagem dinâmica do escoamento de um sistema de elevação por plunger lift

A critical problem in mature gas wells is the liquid loading. As the reservoir pressure decreases, gas superficial velocities decreases and the drag exerted on the liquid phase may become insufficient to bring all the liquid to the surface. Liquid starts to drain downward, flooding the well and increasing the backpressure which decreases the gas superficial velocity and so on. A popular method to remedy this problem is the Plunger Lift. This method consists of dropping the "plunger"to the bottom of the tubing well with the main production valve closed. When the plunger reaches the well bottom the production valve is opened and the plunger carry the liquid to the surface. However, models presented in literature for predicting the behavior in plunger lift are simplistic, in many cases static (not considering the transient effects). Therefore work presents the development and validation of a numerical algorithm to solve one-dimensional compressible in gas wells using the Finite Volume Method and PRIME techniques for treating coupling of pressure and velocity fields. The code will be then used to develop a dynamic model for the plunger lift which includes the transient compressible flow within the well

Extração enzimática de óleo e produção in situ de biodiesel a partir da Moringa oleífera Lam

With the growth and development of modern society, arises the need to search for new raw materials and new technologies which present the "clean" characteristic, and do not harm the environment, but can join the energy needs of industry and transportation. The Moringa oleifera Lam, plant originating from India, and currently present in the Brazilian Northeast, presents itself as a multi-purpose plant, can be used as a coagulant in water treatment, as a natural remedy and as a feedstock for biodiesel production. In this work, Moringa has been used as a raw material for studies on the extraction and subsequently in the synthesis of biodiesel. Studies have been conducted on various techniques of Moringa oil extraction (solvents, mechanical pressing and enzymatic), being specially developed an experimental design for the aqueous extraction with the aid of the enzyme Neutrase© 0.8 L, with the aim of analyzing the influence variable pH (5.5-7.5), temperature (45-55°C), time (16-24 hours) and amount of catalyst (2-5%) on the extraction yield. In relation to study of the synthesis of biodiesel was initially carried out a conventional transesterification (50°C, KOH as a catalyst, methanol and 60 minutes reaction). Next, a study was conducted using the technique of in situ transesterification by using an experimental design variables as temperature (30-60°C), catalyst amount (2-5%), and molar ratio oil / ethanol (1:420-1:600). The extraction technique that achieved the highest extraction yield (35%) was the one that used hexane as a solvent. The extraction using 32% ethanol obtained by mechanical pressing and extraction reached 25% yield. For the enzymatic extraction, the experimental design indicated that the extraction yield was most affected by the effect of the combination of temperature and time. The maximum yield obtained in this extraction was 16%. After the step of obtaining the oil was accomplished the synthesis of biodiesel by the conventional method and the in situ technique. The method of conventional transesterification was obtained a content of 100% and esters by in situ technique was also obtained in 100% in the experimental point 7, with a molar ratio oil / alcohol 1:420, Temperature 60°C in 5% weight KOH with the reaction time of 1.5 h. By the experimental design, it was found that the variable that most influenced the ester content was late the percentage of catalyst. By physico-chemical analysis it was observed that the biodiesel produced by the in situ method fell within the rules of the ANP, therefore this technique feasible, because does not require the preliminary stage of oil extraction and achieves high levels of esters

Cissus sicyoides (princess vine) in the long-term treatment of streptozotocin-diabetic rats

Leaf decoctions of Cissus sicyoides (princess vine) are taken widely as a popular remedy for diabetes mellitus in Brazil, where its common name is 'vegetal insulin'. However, there have been practically no attempts so far to determine scientifically whether it has antidiabetic effects and we decided to administer leaf decoctions, over extended periods, to normal and streptozotocin-diabetic rats, and investigate the effects of this treatment on the physiological and metabolic parameters that are altered in diabetic animals. The experimental model adopted was shown to be appropriate by running a parallel treatment with insulin, which led to expected improvements in several abnormal parameter values. The decoction treatment significantly reduced the intake of both food and fluid and the volume of urine excreted, as well as the levels of blood glucose, urinary glucose and urinary urea, in comparison with controls. Lipid metabolism was not affected by the treatment; nor was the level of hepatic glycogen in diabetic animals, which indicated that the mechanism responsible for the improvement in carbohydrate metabolism, observed in animals treated with the decoction, could not involve inhibition of glycogenolysis and/or stimulation of glycogenesis. The fact that normal animals treated with C. sicyoides exhibited no changes in any of the measured parameters suggests that its mode of action in diabetic animals does not resemble those of sulphonylurea or insulin. It may, however, act in a similar way to biguanide, via inhibition of gluconeogenesis.

O Bullying sob o olhar dos educadores: um estudo em escolas da rede privada de Natal/RN

The school bullying involves all aggressive, intentional, repetitive attitudes, occurring without apparent motivation, adopted by one or more students against another (s) causing pain and anguish, and implemented within an unequal relationship of power, making possible the intimidation of the victim. Its expressions involve defamatory rumors, discrimination, theft or damage to property, harassment, threats, beatings, isolation, exclusion of a person or group, intimidation, intolerance and disrespect. In this study, we sought to identify the design educators have about the bullying, and are known by what means are aware of the problem, is involved when identifying cases of bullying and how to give this speech. This study used for data collection a questionnaire applied to 107 educators from 14 private schools in Natal / RN, who received statistical treatment in the program SPSS and the results analyzed in the light outside of a social and historical reference. Among the results, we found that 83% of the interviewed educators has at least heard about bullying, and the information about the problem are mainly the media, like television, newspapers and magazines. The educators said that the surname and physical attacks are more frequent outbreaks of violence among students and also the most common complaints when they look for help. The necessity for intervention when it identifies a case of bullying is present in 97.03% of respondents and 73.27% of educators are also called by students or school officials to remedy the situations of bullying among students. On the forms of intervention employed, the most common is the conversation and warning the students involved. It is suggested that the intensification of studies related to the subject and the development of actions and programs antibullying involving the school community (educators, parents, students, employees), in partnership with social segments like Tutelar Council and others related to the protection of children and adolescent

Protozoários de vida livre em dois trechos da bacia hidrográfica do rio pirangi (RN): relações com a educação em ciências e preservação

The vast hidric wealth of Brazil gets its watersheds more susceptible to impacts that compromise the water quality, affecting the ecosystem stability of aquatic environments. The decrease in the quality of water resources also results in a decrease of its multiple uses, especially in tourist areas of the coast, where the continuous flow of people to these sites increases even further the probability of inappropriate behavior of both tourists and local residents. Studies regarding the microbiological communities are still scarce, especially on the free-living protozoa that play unique roles in the food chain of aquatic ecosystems. Due to the large role played by this group of microorganisms in aquatic environments, the present study aimed at identifying the genus and species of free-living protozoa present in two sections of the Pium River, east coast of Rio Grande do Norte, making an association between the its occurrence and trophic conditions of the environment in which they are, also checking the bioindicator capacity of these organisms in water quality. It also aimed to conduct a survey with students to identify the main difficulties regarding the knowledge of free-living protozoa and hydric transmission diseases in two public schools near the river studied in the Pium district, county of Parnamirim. The survey was analyzed by means of questionnaires at both schools. Students identified several activities developed Pium river, highlighting its multifunctionality and importance to the region. A total of 76 taxa of free-living protozoa was recorded, of these, 33 were ciliates, 19 flagellates and 24 sarcodia. The spatial and temporal patterns of these organisms to both points studied revealed the bioindicator potentiality of some effective species identified. However, knowledge about the free-living protozoa proved quite lagged, presenting misconceptions that show them as pathogenic organisms exclusively, totally disregarding their ecological role. In order to remedy the flaws existing in students in relation to the functional role of protozoa, workshops were planned on these microorganisms while also addressing issues related to hydric transmission diseases through lectures, recreational activities and interactive presentations. These practical activities of Science Education had the goal of bringing students the context of local water resources, aiming to promote a greater clarification regarding of the functional role of free-living protozoa in aquatic environments
